Abstract

In this paper we will generalize the Kalman rank condition for the null controllability to nn-coupled linear degenerate parabolic systems with constant coefficients, diagonalizable diffusion matrix, and mm-controls. For that we prove a global Carleman estimate of the solution of a scalar 2n2n-order equation then we infer from it an observability inequality for the corresponding adjoint system, and thus the null controllability.
